If someone could make 11% in 24 hours, they wouldn't need anyone's investments. Think about it, you start with $100 and multiply it by 1.11 30 times, that means in the end of the month they would have $2,289. In the next month - $52,400. In the end of the third month - $1,199,446. So, a person with this method and just $100 would become a millionaire in 3 months. What is the logical reason for them to take other people's money and share the profit with them, if they can work for themselves? Or just take a few thousand dollars loan from a bank and become a millionaire even faster. The answer is obvious - no one is making such big returns in this world.
This kind of scheme mostly fall in ponzi-type one. They are banking on gullible users that will join because how can they generate their funds, from other users, right? So if you are at the bottom, the likelihood of losing your funds is high. With such high ROI, most of these sites will be gone once the owner/s collected enough funds for their pocket. So as much as possible don't be enticed by high ROI, because that's not legit.
